Fitment/Interchange

• Ecu will fit 1995 to 1997 Lexus LS400 models with an exact part number match.
• Whether you purchase from Your_Part_Source or another vendor, do not purchase one of these ECUs which hasn't been rebuilt. They all fail and more than likely you are getting a bad unit from a seller who isn't rebuilding them.
